Attracting Butterflies

I'm going to try to attract butterflies to our tiny, north-facing patio. Wish me luck. My first effort -the butterfly bushes- has met with a bit of success. I took a picture of our first butterfly customer:



My second effort is a jerry-rigged butterfly feeder:



No takers at the feeder so far, but it's early days yet. The nectar recipe I found online is 1 part granulated sugar dissolved in 4 parts water boiled several minutes and then cooled. I put a yellow tuffy in the little pot, then hung it up on the planter hook. It's hung over a healthy stand of coleus where I want to plant some milkweed in the Fall.
